ACPI IRQ Holder for PCI IRQ Steering problem

The subject line says it all. I have Win 98SE and an ASUS A7N8X-E motherboard. Win 98 Start-Programs-Accessories-System Tools-System Information-Problem Devices says I have 10 ACPI IRQ Holder for PCI IRQ Steering devices with Device Failure. Looking in Device Manager I find three of them to be associated with IRQ 5, three with IRQ 9, four with IRQ 11.

Everything on the computer is working. My modem, sitting in the second PCI slot, is no problemo. No other PCI devices.

Should I worry? Should I kick back and relax? Should I fix it, and if so, how?
